JOSEPH TRIMBAGH, OF RYE, NEW YORK.

PRINTING-CAMERA.

Application filed May 14, 1915.

To all whom it may concern:

Be it known that I, Josnrrr TRIMBACH, a citizen of the United States,and a resident of Rye, in the county of Vestchester and State of NewYork, have invented certain new and useful Improvements in Printing-Cameras, of which the following is a speci fication.

My invention relates to photography, particularly to means for printingpositives from negatives, and is an improvement over the form shown anddescribed in my application for Letters Patent of the United Statesfiled Jan. 9, 1915, Serial No. 1369. In the form referred to the hoodwas slidably removable from the cabinet, as was also a drawer for thereception of a transparent panel which was adapted to bear upon thenegative and the print paper thereunder, an eXteriorly operable shutterbeing required. In my present form, however, this sliding of the hood iseliminated, as are also the drawer and the shutter, although I mayemploy the shutter if desired, the hood being in permanent and hingedconnection with the cabinet whereby it may be swung backwardly to allowthe substitution of a new negative and, in the event of cut print paperbeing employed, of anew sheet thereof, thus simplifying the operation ofprinting. When a number of prints are to be made from one negative, Iprovide the roll of print paper disclosed in the application aboveidentified, or I may make single positives from separate negatives fromthis roll of sensitized paper as well.

The device is primarily adapted for use in a dim light, as is usual withgas-light papers, but the device contains the printing light or lamp, aswell as a non-actinic lamp which may be used to position the negativeand positive sheets, after which the white light is turned on and theprinting begins.

My invention is fully described in the following specification, of whichthe accompanying drawings form a part, in which like characters refer tolike parts in each of the views, and in which Figure 1 is a perspectiveview of my invention, ready for use; Fig. 2 is a central verticalsection therethrough on a line from front to rear, in operativearrangement of parts; Fig. 3 is an enlarged, fragmentary, sectionaldetail view; Fig. 1 is an enlarged view similar to Fig. 2, but with thehood Specification of Letters Patent.

Patented Nov. 30, 1915.

Serial No. 28,043.

thrown back out of operative position, as for the substitution of a newnegative, new sensitized paper, or both; Fig. 5 is a horizontal, planand section taken on a line above the cabinet, and partly broken away;and Fig. 6 is an enlar ed, fragmentary, section on the line 6-6 of Fig.2.

In the drawings forming a part of this application I have shown oneembodiment of my invention, comprising a cabinet 7 divided into twocompartments 8 and 9 by means of a partition 10, the former of which issomewhat hi her than the latter so that cut-outs 11 result in the sidesof the cabinet as shown in Figs. 1 and at; the compart ment 8 is open atits top and provided with a light-proof lid 12 to permit the insertionof a reel 13 carrying a roll of sensitized paper 14:, and the top of thecompartment 9 being covered by a horizontal plate 15 serving as asupport for the paper 1%, a fingerhole 16 being provided in the frontthereof to allow grasping of said paper to draw it forwardly whendesired.

Secured to each side of the cabinet, at the uppermost points thereof, ishinge 17, which hinges are also connected with the respective sides of aframe 18 filling the cutout portion of the cabinet, said frameconsisting of the sides 19, front 20, back 21 which closes off thecompartment 8 when the frame is in operative position but does not quitetouch the plate 15, a slot 22 resulting to permit the passage of thepaper 14 from the reel to the front of the cabinet; as shown in Fig. 6,the lower edge of the frame 18 is preferably provided with a felt strip18 to render the interior of the device light-proof, and the sides ofthe frame are provided, interiorly thereof, with grooves 23 for thereception of a glass negative or, as shown, of a transparent sheet ofglass 24: to hold the film negative 25 flat against the paper 14, thisbeing made in any desired form.

Carried by the frame 18 is a rectangular bellows 26 surmounted by arigid hood 2'? of truncated pyramidal form which is pro vided with awindow covered by a ruby, orange, or other non-actinic glass 28, the topof the hood being closed by means of a plate 29 carrying two electriclamp sockets 30 and 31 for ruby and white lamps, respectively, providedeach with a switch or having a switch adapted to throw one lamp in andthe other out at will, this not being illustrated as any one of a numberof well known forms may be employed.

The hood 27 is maintained in desired relationship with the frame 18 bymeans of vertical rods 32 carried at the corners of the latter andsleeves 33 carried at the corners of the former and slidably locked onthe respective rods by means of set screws 34: or equivalents, the rods32 being of suflicient length to permit full extension of the bellows 26to move the lamps into desired relationship with the paper 14.

The film negative may be buckled and sprung into place when the hoodsection, including the frame 18 and the bellows, is thrown backwardly onits hinges and, when the hood section is returned to operative position,said negative bears upon the paper 14: which rests upon the plate 15.,and printing may begin. If a glass negative is used, the glass plate 24may be removed to permit the negative to replace the same, and I may,although not shown, provide asuitablecatch for holding the cabinet andframe together tightly during printing. \Vhen a print has been completedthe free end of the paper 1% may be grasped and the exposed paperportion detached by tearing from the body thereof, to undergodevelopment, fixing, and washing, and this printing may be repeatedindefinitely with one or more'negatives within the capacity of the rollpaper, a key 35 being provided for the reel 13.

It will thus be seen that a simple though practical printing cameraresults which is adapted to glass negatives, cut orroll films, as theroll film could be rolled upon the reel with the sensitized paper in adark room preparatory to printing, and to either :cut sheets ofsensitized paper or a continuous roll thereof.

The ruby'lamp may be used to position the paper and in removing thesame, the white lamp being used only for the actual printing, the lampsmay be adjusted toward or from the paper according to the density orcharacter of the negative, or the brilliance of the lamp.

There are no separable parts to be mislaid or lost, and the device maybe collapsed into compact form, as for storage, packing, or shipping;While I have shown certain .details offconstruction, it will be obviousthat I am not limited thereto, but may make changes thereover, withinthe scope of the following claim, without departing from the spirit ofmy invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

A printing camera embodying a cabinet comprising side walls, front wall,rear wall, vertical and horizontal plates forming compartments and acover for one compartment, respectively, said side walls being cut outto form upwardly directed members, hinges carried by said members, aframe carried by said hinges and filling said cut outs, an extensiblelight chamber carried by said frame. and means for holding said chamberin adjusted position with respect to said cabinet and frame, said framebeing adapted to receive a negative, and saidhorizontal plate serving asa support for the sensitized paper.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
